The community classification is made on the Uryu-Numa mire vegetation situated at 43゜42´NL, 141゜37´ EL and 850 m above sea-level. In the present studies, the authors has applied the sociation-association system to the community classification. In the classification, sociations are first distinguished by the dominants or the constant species, or often by the combination of them with the habitat indicators. Then, the sociations distinguished are grouped into associations by the characteristic species or sometimes by their combination with the plants which are usually conspicuous physiognomically. In the classification, the authors stress that the sociation is the subunit of the association and that it is a basic unit available for field practice. As the higher hierarchical ranks above the association have not been identified in their classification, the authors do not refer to them in the present paper. The plant communities classified are as follows
